Will-o'-the-wisp

A will-o'-the-wisp is a faerie that is more often seen as just a pale floating light, something that attracts a traveler's attention and then leads the traveler off the path and into a thick wood or otherwise unfamiliar place, where it is easy to get lost irrevocably. Often they will continue to tease the traveler until they get their intended result. Will-o'the-wisps are also known as merry moon dancers or ignis fatuus.

The Will O' The Wisp is a mischievous spirit that likes to trick night travellers into following his glowing, misty form into ditches, forests and swamps where they eventually get completely lost and helpless.
